摘　　要：针对新能源汽车电驱部分的能耗问题,对电驱系统相关检测方法和评价指标进行了研究,提出了针对新能源汽车不同工况条件下的电机及其控制器能耗检测和评价指标。对新能源汽车整车节能技术进行了归纳,分析了电驱系统在不同工况条件下的能耗特征,阐述了电驱系统的性能参数对不同整车节能工况的影响。对电驱系统的电气原理图进行了简单分析,提出了对系统能量回收过程的工作范围和转换效率都有着重要影响的电机漏感等技术参数。利用课题设计的电机检测台架对具体的电机及其控制器产品进行试验,得出了不同转速和转矩条件下电驱系统的能量转换效率,分析了不同节能工况条件下电驱系统的典型效率值。研究结果表明,基于不同整车工况的电驱系统综合能耗检测方法对降低新能源汽车能耗有着重要意义。Aiming at the energy consumption of new energy vehicles,testing methods and the evaluation index of motor drive systems were studied,and different evaluation indexes of motors and its controllers were proposed for new energy vehicles under different operating conditions. Based on the summary of energy saving technologies of new energy vehicles,energy consumption characteristics of motor drive system were analyzed and the influence on different energy saving condition of the parameters was described. After a simple analysis of the electrical diagram of a electric motor system,parameters including with motor leakage value were important to the operating range and conversion efficiency of the system energy recovery mode. The specific motor and its controller were tested by using the motor testing bench designed by the research group. The experimental results indicate that typical efficiency value of motor drive system under different energy saving mode can be calculated by the energy conversion efficiency distribution map. The research results indicate that the comprehensive energy consumption test method based on different vehicle conditions is of great significance to reduce the energy consumption of new energy vehicles.
